Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
French Fruit Cake
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix together the butter and sugar until creamy.
Add the beaten eggs, sweet cream, and sweet wine; mix well.
Dissolve the baking soda in a little boiling water and add to the mixture.
Stir in the raisins, currants, citron, flour, and spices until combined.
Bake
Pour the batter into a greased baking pan and bake for about 1 hour or until a toothpick comes out clean.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set during baking.
- Butter
- Adds richness and tenderness when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a creamy, aerated base with the butter.
- Baking soda
- Reacts with the batter to help it rise and lighten during baking.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Dissolving the baking soda. Baking soda needs an acid to react and lift the batter, and it should be fully dissolved so it distributes evenly and doesn't leave pockets or bitter spots. Mixing it in thoroughly before adding the flour helps the cake rise evenly.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, cream, wine, raisin, flour):
- Vanillafits better

- Currantthe original
Fit is the average pairing score against butter, sugar, egg, cream, wine, raisin, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
